Biotinylated Human Serum Albumin Protein, His,Avitag™ (MALS verified)
分子别名(Synonym)
Serum albumin,ALB,Alb
表达区间及表达系统(Source)
Biotinylated Human Serum Albumin, His,Avitag (HSA-H82E3) is expressed from human 293 cells (HEK293). It contains AA Asp 25 - Leu 609 (Accession # P02768-1).
Predicted N-terminus: Asp 25
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 70.2 kDa. The protein migrates as 70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
标记(Labeling)
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白标记度(Protein Ratio)
Passed as determined by the HABA assay / binding ELISA.
纯度(Purity)
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
血清白蛋白(SA),亦称ALB,是血浆主要蛋白质,对水、Ca²⁺、Na⁺、K⁺、脂肪酸、激素、胆红素及药物具有优异结合能力。其核心功能在于维持血液胶体渗透压平衡,同时作为血浆中主要的锌转运蛋白,可结合约80%的血浆锌离子。当白蛋白结构发生变异时,锌结合能力增强可导致血液锌浓度无症状性升高。
白蛋白缺陷会引发家族性白蛋白异常性高甲状腺素血症——这是一种甲状腺功能正常的高甲状腺素血症,源于白蛋白对甲状腺素(T4)结合亲和力异常升高。该疾病是高加索人群遗传性甲状腺功能正常的高甲状腺素血症最常见病因。
